There is this thing humans do when speaking or writing. It's called the 'figurative'.
Obviously, I am not an actual crow. I am surprised you didn't realize that until now.
There is something else that humans do: they hurl abuse and insults, apropos of nothing, and for no easily visible reason. Hence your accusation of 'poseur', which I am certainly not. I pose as nothing and at nothing.
The name 'crow' refers to the attributes of an actual, historical crow, that I found so superior to human traits, that I adopted them, in order to hopefully become more than I started out as. Namely a 'human'.
